TYPICAL PERFORMANCE CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: This is the temperature coeffi cient of the internal feedback
resistors assuming a temperature independent external resistor (R
IN
).
Note 3: The input common mode voltage is the average of the voltages
applied to the external resistors (R
IN
). Specifi cation guaranteed for R
IN
≥ 402. For ±5V supplies, the minimum input common mode voltage is
guaranteed by design to reach –5V.
Note 4: Distortion is measured differentially using a single-ended stimulus.
The input common mode voltage, the voltage at V
OCM
, and the voltage at
V
MID
are equal to one half of the total power supply voltage.
Note 5: Output common mode voltage is the average of the voltages at
Pins 4 and 5. The output common mode voltage is equal to the voltage
applied to Pin 2.
Note 6: The LT6600C-2.5 is guaranteed functional over the operating
temperature range of –40°C to 85°C.
Note 7: The LT6600C-2.5 is guaranteed to meet specifi ed performance
from 0°C to 70°C and is designed, characterized and expected to meet
specifi ed performance from –40°C and 85°C, but is not tested or QA
sampled at these temperatures. The LT6600I-2.5 is guaranteed to meet
specifi ed performance from –40°C to 85°C.
Note 8: The inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 1.4V, the input current should be limited to less than
10mA.
